Moron-PUMP.

- Specification of Letters Patent.

Patented March 2, 1909.

A Application filed, June 28, 1907.v Serial No. 381,297.

citizenof the United States, residin at Lansing, county of Ingham, State of Michigan, have invented certain new and useful Improvements in Motor-Pumps, of which v the following is a specification.

This invention relates to improvements in motor pumps.

:The main object of this invention is to provide an improved motor pump which is compact and durable and at the same time one which is of relatively hi h power, very simple in structure and durab e in use.

Further objects, and -objects relating to details of construction, will definitely appear from the detailed .description to follow. I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

. A structure embodying the features of my invention, is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,

Figure 1 is a side elevation of a structure embodying the features of my invention; Fig. 2 isan end elevation thereof looking from the right of Fig. 1; Fig. 3 is a detail vertical section taken onv a line corresponding to line 33 of Fig. 2; and Fig. 4: is an enlarged detail section taken on a line corresponding to li.ne 4-44: of Fig. 1. I

In the drawings similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the base 1 is provided with a shaft pedestal 2 at one end and with a pump pedestal 3 at the other. The engine 4 is provided wiih-a suitable base 5, which is secured upon thebase, 1 between thepedestals 2 and 3, as clearly appears from the drawing. The engine shaft .6 is preferably. provided with a balance wheel --7 at each end, the balance wheel at Jone side'serving as a belt wheel for the belt 8 by which the fan 9 is driven. On the engine shaft is a pinion 10 arranged to mesh with a pinion 11 on the shaft 12 mounted on the bearing pedestal 2. The shaft 12 1s provided with a crank disk 13, the crank pin 14 of which is arranged in theslot 17 in the rality of holes 18 adapted to receive the crank pin so that the crank pin may be adjusted thereon, thereby varying the stroke of the lever. v

The pump 19 is arranged in a horizontal position on the pedestal 3. The piston rod 20 of the pump is connected to the lever preferably by a connecting rod comprisin the adjustable section ,21, which is threade into the coupling sections 22 and 24, the coupling section 22 being secured by a pivot 23 to the piston rod and the coupling section being connected by the pivot 25 to the lever 15. The section 21 is-threaded' into the sections 22 and 24 so that by turning the same the length of the coupling rod may be regulated. The outer end of the piston rod is supported by a bearing 26 carried by the arms 27. The pivot 23 for the couplin rod is secured to, the piston rod "inside of-this bearing-so that the piston rod has a straight reciprocatory motion and does not bind in its bearings.

The storage or pressure chamber 28 is suit ably connected to the pump and is provided with discharge pipes 29 and 30, which are controlled by a suitablevalve as 31.. I preferably provide a suitable pressure gage, as 32.

By thus arranging the parts I secure a very compact structure and one which is lightand readily portable. W'hile I have particularly designed the same as a force pump for use in spraying or the like where considerable pressure is desired, it is, of' course, adapted for use in various other relations, as for the operation of pneumatic machinery, and the like, or as an exhaust pump, when provided with suitable connections. r

I have illustrated and described my improvements in detail in the form preferred by me, though I am aware that the structure illustrated and described is capable of considerable variation in structural details without departing from my invention.

Having thus described my invention, what I claim as new-and desire to secure by Letters Patent, is:

1. In a portable pumping device, bination with'a portable-base having a hearing pedestal at one end thereof and a pump the comsaid bearing pedestal; gear connections'for crank disk on the said shaft arranged at the said crank disk; a crank pin on said crank said nnection for said engine and raft, for Miipose specified.
